John,
Listen....people, even professionals, really have no business telling you (us) how you are going to feel or what you can "for sure" expect. First of all, has she been through it herself. Second, we are ALL different. There probably are a handful of folks on here that all share the SAME side effects. A few out of thousands. Please don't be defeated before you get started.
You do need to vent. WE know your peeved. We've all been or still are peeved, that's why it's so important to have each other. The things you are feeling and saying are very familiar to all of us. You can get through this and attitude makes all the difference in the world. It's ok to get ticked. Scream, like you did, say your sorry and pick up and move on. Before you know it you'll be done and a few months later you'll be amazed how well you did.
Please stay on here and yell all you want. We KNOW!!! We've been there.
Kathy
